Title: Elastic surface wave element
Inventor: FUJITA YUUJI
IPC: H03H9/25
Filed: 1982-05-14
Abstract: PURPOSE:To improve the amplitude frequency characteristics of a low frequency area by arranging comb-like electrodes so that the phase surface of a signal excited by the electrodes and reflected by an end surface is shifted from the phase surface of a signal excited by the electrodes. CONSTITUTION:The comb-like electrodes 2, 3 having inclination theta from the end surface of a base plate 1 consisting of a lithium niobate monocrystal plate are attached to the surface of the base plate 1. When a signal is supplied to the comb-like electrode 2, its excited wave is advanced in the horizontal direction of the electrode 2. The excited wave advanced in the reversed direction against the electrode 3 is absorbed by an acoustical absorbent 5, but a part of the exicted wave is reflected by the end surface AB of the base plate 1. The signal reflected by the end surface AB is absorbed again by the acoustical absorbent 5 and then advanced in the direction of the electrode 3. Since the inclination theta is determined so that the equiphase surface of a signal excited by the electrode 2 is shifted from that of a reflected wave from the end surface AB, fine characteristics can be obtained even if the size of the base plate 1 is reduced and the length of the acoustical adsorbents 5, 6 is unsufficient.

     CONSTITUTION: A roller chain 1 comprises two steel pin link plates 2 and roller link plates 6 which are connected through a pin 3. The pin 3 is made of a medium carbon steel or a medium carbon alloy steel. After the pin is heated together with metalic chrome and KBF 4  for a prescribed period, it is air cooled, hardened and then tempered under a prescribed temperature, so that the substrate phase of a chrome diffused surface layer 12 of the pin may consist of the ferrite α. Also in this substrate phase are diffused numerous minute granular chromium carbide.  Thus the pin 3 or other bearing members is improved in corrosion and wear resistances.

Title: Defoaming device for steel strip washing liquid
Inventor: SAKABA NORIO
IPC: C23G1/14
Filed: 1996-04-02
Abstract: PROBLEM TO BE SOLVED: To surely defoam a steel strip washing liquid and to prevent the overflow of foam at a low cost by increasing the velocity of introduced foam flow in a throttling section to shear and rupture the foam, further introducing the flow into a defoaming chamber, bringing the flow into collision against net films for rupturing foam erected therein, thereby rupturing the foam. SOLUTION: The steel strip washing liquid contg. a large amt. of the foam generated in the washing line of continuous heat treatment equipment for the steel strip is introduced via an inlet side conduit 1 into the defoaming chamber 3. The throttling section 2 for increasing the velocity of the foam flow is formed at the inlet side conduit 1. A required number of the net films 5 for rupturing foam are disposed in the direction of shutting off the progression of the introduced foam in the defoaming chamber 3 apart spacing parts 10 in the upper part. The velocity of the foam flow is increased in the throttling section 2 and the greater part of the foam is sheared and ruptured by the high-velocity flow. At this time, the ratio of the sectional area A1 of the inlet side conduit 1 and the sectional area A2 of the throttling section 2 is preferably set at about A1 /A2 =2 to 20.  The unruptured foam and the foam 4 made finer are then admitted at the high velocity into the defoaming chamber 3 and are brought into collision against the erected net films 5 for rupturing foam, by which the foam is ruptured. The mists generated at this time are discharged by a blower 7 from the spacing parts 10 in the upper part. The defoamed washing liquid is recovered from a discharge pipe 6.

Abstract: PURPOSE:To perform monitoring operation effectively, by detecting the signal generated in the 1st image pickup mode of a pyroelectric type image pickup device, controlling the rotation of a chopper disposed on the front surface of the pyroelectric image pickup device in accordance with the detected signal and converting the mode to the 2nd image pickup mode. CONSTITUTION:If there is an abrupt change in the movement of an object having a certain temp. or the temp. of a still object in front of a photographic lens, an instantaneous electric signal 17 corresponding to said change is outputted by a waveform circuit 5 in a signal processing circuit. The signal is applied as a trigger signal 17 for changing over of image pickup modes to a change-over circuit 13 for image pickup modes. A logical circuit operates so as to shift the 1st image pickup mode (panning mode) to the 2nd image pickup mode (chopper mode). The output of the circuit 13 is applied to a chopper driving motor 14, which rotates a chopper 15 to a chopper mode. The camera is monitored in the panning mode and when the change in the temp. state arises, the panning mode is changed over to the chopper mode in parallel with alarming; therefore, the efficiency in the monitoring operation is improved, the deterioration in the chopper mechanism is prevented and the electric power consumption for driving the chopper is reduced.

Title: Image processor
Inventor: SATO KAZUHISA
IPC: H04N1/21
Filed: 1993-03-17
Abstract: PURPOSE:To prevent memory overflow error by setting an optimum recording area based on an input image size, immediately storing compressed data together with the compression of inputted image data and correcting the storage area corresponding to the amount of these data. CONSTITUTION:An image reader 11 inputs images as image data and an input image data amount counter 12 decides the size. A compressor 13 compresses the input image data and stores them in an image memory 18. At such a time, a compressed image data amount counter 14 counts the amount of compressed data. Then, a control circuit 17 manages the data stored area units and empty areas of the memory 18 and stores the compressed data by selecting the area for storing the compressed data out of the empty areas based on the input image size decided by the counter 12. After the storage, the storage area of compressed data is corrected based on the data amount of compressed data. Thus, as a result, the compressed data are stored in the empty area provided with the optimum storage area even when the amount of compressed data is not fixed at a time point to input images.

Title: All circumference observation optical device
Inventor: MURAKAMI KENTARO
IPC: G03B37/00
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To restrain reflected light (glare) from the water surface by inserting a polarizing plate between an image rotator for rotating an image and a one- dimensional sensor. SOLUTION: A wide-angle lens 1 forms the image of an object within the range where the angle of visibility (angle of view) is >=180 deg. as a circular image on an image surface 4. A one-dimensional sensor 5 is arranged on the surface 4 and an image rotator 2 is arranged in luminous flux at the rear of the lens 1. By rotating the image rotator 2, the image on the surface 4 is rotated centering an optical axis. By such rotation, the image on the sensor 5 is scanned in a turning direction. At such a time, a polarizing plate 3 is inserted in front of the sensor 5. By changing the angle of the plate 3 fit to the sensor 5 so that luminous flux having polarization parallel with the turning direction may not pass, reflection on the water surface is restrained when the water surface is parallel with the turning direction.  Even if the water surface has an angle to the turning direction, the reflected light from the water surface is restrained by changing the angle of the plate 3.
